Host:
- test first: a new version is tested where it lies; only an installed
version goes to versions/, and instances run from there
- data/ and public/ are shared by all versions; no snapshots; rollback
restores code only
- no re-delivery, status.json, list, remove/archive, smoke test, data/
hiding, or stdin timeout; rollback needs a version
- supervisor.rs split out; one place for installing a version
- init only writes the agent folder; run installs it like any actor
- console: @actor, text to the agent, /help, /quit
Agent:
- every text goes out as a broadcast; 5-line prompt; 5 tools that describe
themselves; turn.json only marks an active turn
Docs: PROTOCOL.md, README.md, DECISIONS.md, AGENTS.md rewritten.
Examples: only notes and notes-v2.
- one live instance per actor: check after the lock; dropping an instance kills it
- state snapshots keep target/ and .git/; only source copies skip them
- one shutdown deadline; output during shutdown is still routed
- deliveries route stdout meanwhile; a stuck stdin kills the instance
(no partial lines) and the sender gets undeliverable; control requests
are not blocked by a stuck delivery
- Host::stop aborts running broker and cargo requests first
- compile a version before installing it; roll back if it does not start
- unique archive names; a failed archive keeps the actor manageable
- commit on close: truncate without create; directory renames
- candidates see SAUSAGE_VERSION and the existing state of a new actor
- the host publishes PROTOCOL.md at /actor/broker/public/
- actor/<id>/ holds actor.wasm, actor.json, source/, public/, data/, versions/
- the broker boots by scanning actor/; a changed actor.wasm is an upgrade,
a rejected one stays in versions/ with a reason and the files come back
- /actor hides every data/ folder
- subscriptions live in the subscriber's actor.json
- cargo installs the SDK and points sausage-actor at it; no build limits
- PROTOCOL.md
Imported from the spike branch, with:
- a library crate (Host API) for the CLI and the tests
- JSON test scenarios for candidates
- commit on close only for new or truncated files
- a Nix flake: nix run -- init, nix run -- run
